"Why is it wrong to want to check that what you are buying has not been half eaten by corn worms?"
"I do this, shame on me, or not. I peel back the shucks just enough to reveal the end of the cob. If it is missing kernels or has very tough woody kernels ("cow corn") I put it back. There's gotta be a reason that my local supermarket can charge $2.99 for a pre shucked four pack of cobs you can get in the shucks at 50 cents or less."Let me explain. It's like checking eggs by cracking them open in the store. Yes, you will avoid bad eggs this way, but you'll ruin your good ones in the process, and leave your fellow customers with ruined eggs, as well.
1. There aren't that many truly bad ears.
2. Due to #1, the vast majority of discarded ears have merely cosmetic issues. People claim to be avoiding worms, but what they're actually doing is searching for a certain look. God forbid there should be a few misshapen or under-grown kernels at the tip.
3. Husks are nature's ideal way of delaying the processes of drying and of conversion of sugar to starch (much as shells are the perfect means of keeping eggs fresh). By ripping them open, you lose that defense, and your corn will go bad much, much faster. You've turned a lifespan of a couple days into a lifespan of hours, even minutes. And consider the corn you've left for strangers. If you've done your damage at, say 10 am, late afternoon shoppers are stuck with shitty corn. (note: "replacing your divot" so to speak - taking only a small peek and trying to rewrap the husk - is ineffective. The seal's broken, period).
4. This forces the store to throw out tons of corn before its time. A plague of human locusts force American retailers to throw out mountains of corn before its time. Vast quantities of water and carbon are wasted due to the mulish assertion of consumer's perceived right to winnow through haystacks of corn for that magical, legendary, perfect ear. Viable, delicious food is blithely turned into garbage for no good reason, and at the cost of everyone's freshness, including the consumer's own (this is game theory where all parties lose).
5. You know how at home, a bit of silk always winds up on your floor, and it's tricky to clean up every last strand? Consider the stores. You're turning their floors into a sticky disgusting mess. Cleaning that involves yet more water and more carbon.
6. Who do you think pays for those mountains of needlessly ruined corn, and for the titanic efforts to clean up the ever-expanding web of corn silk on grocery floors?
